JOHN B. ADT, OF BALTIMORE, MARYLAND.

TOBACCO-CUTTER.

SPECIFICATION forming part of Letters Patent No. 233,829, dated November2, 1880.

Application filed July 26, 1880. (No model.)

To all whom it may concern:

Be it known that I, JOHN B. ADT, of the cityof Baltimore and State ofMaryland, have invented an Improved Tobacco Cutter, of which thefollowing is a specification; and I do hereby declare that in the sameis contained a full, clear, and exact description of my said invention,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

This invention relates to certain improvements in a machine for reducingleaf to smoking tobacco; and it, briefly stated, consists in a rotarycutting device inclosed by a revoluble cylindrical sieve, into which thetobacco-leaf to be cut is introduced, and which sieve is provided withan inwardly-projecting flange, which, in the revolution of the sieve,conducts only such tobacco to the said cutting device as is too large topass through the interstices of the sieve.

It further consists in providing the said sieve with exterior annularprojections and grooved rollers adapted to lit the said projections andsupport the said sieve, as will hereinafter fully appear.

In the further description of my said invention which follows referenceis made to the accompanying drawings, forming a part hereof, and inwhich Figure 1 is a cross or transverse section of the improved machine.Fig. 2 is a top view of the same with the upper part of the outer casingremoved. Fig. 3 is a longitudinal section of the machine. Fig. 4 is apartly sectional view of parts of the invention on an enlarged scale.

Similar letters of reference indicate similar parts in all the views.

A is the frame of the machine. B B are shafts extending transversely ofthe frame A and connected by means of gear-wheels O U- The shaftsB areeach provided with a wooden drum, D, to which are secured circularknives E.

F is the cylindrical sieve, consisting of a piece of wirecloth attachedat its ends to flanges a, which are adapted as pulleys to receive thebelts by means of which the sieve is revolved. The sieve F rests uponfour wheels or rollers, G, and to prevent displacement of the sieve theflanges a are provided with annular projections I), which fit in groovesin the edges of the rollers.

One of the shafts Bis furnished with a driving-pulley, H, through themedium of which the machine is put in operation. A second shaft, I,located below the sieve and driven by a belt from the shaft B, is usedto communicate movement to the sieve by means of belts, as shown.

K is a shaker or tray, consisting of a skeleton-frame, over which isstretched wire-cloth of a finer mesh than the sieve-wire, which receivesits motion from acrank-shaft, L, driven in any suitable manner. Thistray is merely to remove dust from the smoking-tobacco as delivered fromthe revoluble sieve. The upper part of the sieve is covered by a casing,M, (shown in Figs. 1 and 3,) but which is removed in Fig. 2.

Parts of the machine not yet alluded to will be described in thedescription of the operation of the invention which follows.

The machine being placed in operation by means of the driving-pulley H,the tobacco to be cut is introduced to the interior of the sieve througha hopper, N. As the sieve revolves the tobacco contained therein iselevated so as to fall on the cutters, which reduce a portion of it tothe required size. To enforce the elevation of the tobacco in therotation of the sieve, inwardly-projecting flanges areused, one of whichis shown in the drawings, Fig. 1, and represented by-c. In the continuedoperation of the machine the tobacco which is reduced to the requiredsize by the action of the cutters is discharged through the sieve, whilethe larger pieces are elevated to the knives and recut. By this meansonly such particles of leaf as are too large to pass through theinterstices of the circular sieve are cut. Consequently there is nowaste from the reduction of tobacco to dust or to particles too smallfor use.

I claim as my invention 1. In a machine for cutting tobacco, a cuttingdevice, an inclosing revoluble sieve adapted to receive the tobacco tobe cut and provided with an inwardly-projecting flange to elevate thetobacco to the said cutting de- 3. In a machine for cutting tobacco, are voluble sieve having an inwardly-projecting flange and annularprojections on its outer sur- I 5 face, combined with a series ofsupporting grooved rollers and mechanism for effecting the revolution ofthe said sieve, substantially as and for the purpose herein specified.

JOHN B. ADT.
